feat(editor): auto-texture roads with cobblestone on flatten

Browse source 
- paintAlongPath(): paints a texture along a line segment with
  configurable width and quadratic edge falloff
- Road mode now automatically applies Elwynn cobblestone texture
  when flattening a road path (flatten + texture in one operation)
- Quick distance check skips chunks far from the path for performance
- Alpha blending uses max() so overlapping paths don't wash out
